Question

Consider two regions of space containing a static electric field, region A and region B. In region A the equipotential lines are more closely spaced than those in region B. What can be said about the relative strength of the electric field in the two regions? The electric field in region A is stronger than in region B. The electric field strength is unrelated to the spacing of the equipotential lines The electric field is directly proportional to the value of the potential in a given region of space. Therefore, more information is required to answer the above question. Both C and D Equipotential lines are always _______ to electric field lines. parallel perpendicular at a45 degree angle None of the above In the presence of a static electric field, a conducting surface contains no charge contains charge is an equipotential Both A and C Both B and C none of the above

Explanation / Answer

1.E

2. Perpendicular(B)

3. D. Because in conductors electrons are free to move and when placed in static electric field the positive and negative charges move in opposite directions thus making zero electric field and thus an equipotential surface.
